Molecular Silicon Clusters

“…Silicon and its compounds show diverse structural, physical, and chemical properties and are thus applicable in most areas of everyday life: Silicon dioxide (sand) and the silicates provide the basis for building materials like glass, ceramics, − or concrete. , Polysiloxanes, polymers with a backbone of alternating silicon and oxygen atoms, colloquially known as silicones, are similarly multifaceted and used, for instance, as lubricants, heat-transfer media, rubbers, paint binders, medical implants, seals, or insulators. , Silicon in its elemental form represents the prototypical semiconductor. Our information technology-centered society would be inconceivable without modern high-performance Si-based devices such as photovoltaic cells, thin-film transistors, or microprocessors. − In order to meet the resulting high demand, silicon is industrially produced at a huge scale (6.7 million metric tons in 2018 worldwide) .…”
